Well, if you think about it, unless you upgrade, many times your e-ring will not be reflective of your current income/possessions. If you continually get salary increases, you should have more money to spend as time goes on, which could increase the value of things that you buy. That's part of why I will never upgrade...it's a reflection of exactly where we were at the point of engagement in our lives. If I got a bigger stone, I would either get a different shape for a RHR or maybe make it a necklace. Of course, I have no problem if other people decide to upgrade, but it shouldn't be based on the value of your other jewelry IMO, but again, I guess it depends on how sentimental you are about your original ring
It is also insane to me that they refused to halo a J colored stone. j is still good quality and near colorless. Makes no sense. Maybe you can look for a smaller halo which still makes it appear as a solitaire but increases the look of the stone's size? I have a Tacori 2620 and you can barely see the halo but it makes the diamond look larger. Tacori also allows you to just buy the setting, then a jeweler can set your current stone in it
